No he doesn't because he doesn't understand jack shit. We can piss and moan about China forcing companies to have to partner with Chinese companies to sell and produce stuff there, but they have a good reason for doing that (lots of western corporations were raiding Asian countries to exploit their workers so they could boost their profit margins, China is just saying ok if you're gonna do that shit you're gonna have to do something for us; essentially they gave their IP theft legitimacy). They're not locked out, but they have to work deals (just like they had to do to get into the US markets, something people also ignore). The US had a lot of partnerships with Japanese companies due to WWII. Sega for instance was actually a partnership that started out of importing arcade type of games (back before arcades really existed, think it predated even like pinball games) for US servicemen in Japan. We profited massively post WWII (which is why all the bitching and moaning that we haven't kept pace with that level of surplus is stupid because it fundamentally ignores the advantage we had for a few decades there).
Japanese and German car companies actually have a lot of production in the US. BMW is the largest automotive exporter in the US (meaning exporting cars made in the US). Things will change though (Ford has already announced big changes, think the Focus is going to be made in Europe next gen and then exported all over the world, the Fusion might be killed or is going to be made in China and not even sold in the US), because, get this, the world is changing. If we throw tantrums and don't work with other countries and actively sabotage trade deals, we're going to be the ones that get fucked. The days of us being able to force trade deals that mainly benefit us are over and there's reasons that have nothing to do with some nefarious plot to undermine America. Its because the world has developed and has been stabilizing and been building itself up a lot. Because, unsurprisingly, cutting down on major wars has helped bring peace and stability. But seems that people want to blow that all to hell so they can help some of the wealthiest countries pad their pockets a bit more.
Too many people in the US are fucking idiots and don't seem to realize how much of the developments we claim we hijacked from others (hello Nazi engineers that literally were the reason we won the space race), or were collaborations (often done by people more interested in development for humankind and not any nationality; hell many were just nerds that wanted to do cool stuff, the US just had certain things that made it appealing, one of which was political stability and government that wanted them there, something that has been changing for the worse for that). That's not marginalizing the US's role in it, its just being rational about why things went the way it did. And yet we have politicians ignoring that and wanting to do exactly the type of thing that pushes those people away.
Many of them were very high level scientific education institution advancements, something that Republicans have been outright condemning for a few decades now (not all of them, but there's been a general movement within them on this, and they're now openly spouting that type of rhetoric; the great irony is them condemning "liberal elite" while the conservative elite pillage the country every other decade). And a lot of others came from research groups that corporations let tinker away (Bell Labs, Xerox PARC), only now so they can maximize shareholder profits (because if they don't then they break the companies apart) many corporations have done away with that type of stuff or at least massively scaled it back (there's a reason why Google is tied to so much of that type of stuff now, because they're one of the few still doing it on anything more than a fluff level). That's why we're starting to lose our advantages. Its exactly the type of Capitalism spouted by Republicans and Turmp that is doing the shit that they're blaming on other things. And they refuse to see it.
